just updated to jaunty and it seems to install the unstripped packages by default, so the -dev packages conflict with that and to install them you need to remove software like blender, vlc, gstreamer-ffmpeg... then you can install it again of course, but it should be better that in the update the normal libxxx packages get installed or that the -dev pacakges could be installed using the unstripped ones.
